不能将类型'[RKDataStreamingMask]的值转换为预期的参数类型'RKDataStreamingMask'

Xcode 7 and my code:

Xcode 7和我的代码:

func sendSetDataStreamingCommand {
let mask = RKDataStreamingMask.AccelerometerFilteredAll |
RKDataStreamingMask.IMUAnglesFilteredAll |
RKDataStreamingMask.QuaternionAll ;
self.robot.enableSensors(mask,atStreamingRate:RKStreamingRate.DataStreamingRate10);
}

the warning is :

警告:

swift Binary operator '|' cannot be applied to two UIViewAutoresizing operands

then change code:

然后改变代码:

func sendSetDataStreamingCommand {
let mask=[RKDataStreamingMask.AccelerometerFilteredAll,
RKDataStreamingMask.IMUAnglesFilteredAll,
RKDataStreamingMask.QuaternionAll]
self.robot.enableSensors(mask,atStreamingRate:RKStreamingRate.DataStreamingRate10);
}

then warning in last sentence is :

最后一句的警告是:

Cannot convert value of type '[RKDataStreamingMask]' to expected argument type 'RKDataStreamingMask'

Please teach me how to do ?Thanks.

请教我怎么做?谢谢。

To declare a variable containing multiple members of OptionSetType you have to annotate the type explicitly, otherwise the square brackets are treated as an array.

要声明一个包含OptionSetType多个成员的变量，必须显式地注释该类型，否则方括号将被视为数组。

let mask : RKDataStreamingMask = [.AccelerometerFilteredAll, .IMUAnglesFilteredAll, .QuaternionAll]
